Abstract:
When the reliability of multi-arch tunnel is calculated according to load structure method, it is a significant task to further study because of the question for calculation of pressure of surrounding rock on multi-arch tunnel according to current Code for Design of Road Tunnel. First, the boundary between deep and shallow depth of multi-arch tunnel is discussed. Second, it is compared with ordinary theories of pressure of surrounding rock. The problems between them are found out. Last, the improved calculation of pressure of surrounding rock on multi-arch tunnel is presented. The effects induced by the improved calculation are analyzed. The results show that it acts as reference for design and calculation for multi-arch and large span tunnel in future. 3 tabs, 4 figs, 14 refs.
